Hi. Villain is a fish 61/4 WTSD 33% his river aggresion 3.5 and overral agression 1.1 so I think he likes to steal some pots and later even noticed that. Flop and turn obviously standard line but I have decided to make a trick on a river he might like to chop it
. Don't really know if it even works because haven't many situations like this. In your opinion, how to extract max value? Check to induce bluff or to make 1/2 pot - pot sized bet? Probably second one? Thanks

yeah, he may call to your overbet shove, but very likely he thinks you have nuts and fold
If he is aggressive then you can try going c/rai on the river, I think they try very often betting pot with air there and very likely also calling then shove
If I´d bet river, then I´d make it 7$. Doubt he is going to shove, but very likely call your down
